Answer 1

let's start with {A}

(25)^2=(24)^2+(7)^2

625=576+49

625=625

so (a) is a right triangle✓

{B}

(3)^2=(1)^2+(1)^2

9=1+1

9 is not equal to 3

so (b) is not a right triangle×

{C}

(25)^2=(15)^2+(20)^2

625=225+400

625=625

so (c) is a right triangle✓

{D}

(18)^2=(12)^2+(15)^2

324=144+225

324 is not equal to 369

so (d) is not a right triangle×

{E}

(13)^2=(12)^2+(5)^2

169=144+25

169=169

so (e) is a right triangle✓

(F)

(45)^2=(36)^2+(27)^2

2025=1296+729

2025=2025

so (f) is a right triangle✓

ALL THE SOLUTION IS BASED ON PYTHAGORAS THEOREM

WHICH MEANS THE SQUARE OF BIGGEST SIDE IS EQUAL TO THE SUM OF SQUARE OF THE REMAINING SIDES.
